Thank you for your great support..!!

Will you please help me for connecting multiple peripheral??

Great to hear that you figured it out! Good luck with further development.

I am able to sent all sensor data to multilink central by referring ble_nus_c_evt_handler and other event handler also. But now still facing issue for connecting more than one peripheral to one central.

How i connect multiple peripheral connection with one central i checked connection handle.

Which event and function use for multiple and concurrent connection for peripheral side so i will look and debug where should i wrong.

Thanks you so much..!!!

Take a look at the ble_nus_c_evt_handler, especially the BLE_NUS_C_EVT_DISCOVERY_COMPLETE case & the ble_nus_c_tx_notif_enable() function inside main.c of the uart central example. In that same function, there is a log print which says that the central is connected to a peripheral device that uses the Nordic UART service.

Hi Bjorn,

I solved issue by self which is notification is not enabled. So now discovery completed log is generated and also RX event generated.

But i have question how i know at central side notification is enable and now ready for sending data from peripheral.

Is it any trigger option for once peripheral connected to central and also their notification is enabled then i want to send sensor value.

Thanks...!!!

Thanks for your reply,

I checked as you provided above link and i have already done changes in my peripheral as well as central code.

I noticed at central side the notification is not enabled the "ble_nus_c_evt_handler" is not generated in central why it so happen.

could you please provide me small sending function snippet for peripheral. I want to send message directly once connected event generated in peripheral.

Is problem for communication if i use nRF52832 DK for multilink and sparkfun nRF52832 custom board for peripheral because both of board file is different. If yes for sparkfun how i add custom board.h file.

We have less time for develop solution.

Thanks..!!!

For a good example, I would see how the uart central & uart peripheral examples communicate with each other & add uart support for the multilink example like in the link you posted. Once you have understood those examples, it should not be too difficult to add uart support the the multilink central example.
